The timer spt-switch command sets the interval for checking whether the rate for transmitting multicast data exceeds the threshold before the switchover from the rendezvous point tree (RPT) to the shortest path tree (SPT).
The undo timer spt-switch command restores the default value of the interval.
| Parameter | Description | Value |
|---|---|---|
| interval | Specifies the interval for checking whether the rate for transmitting multicast data exceeds the threshold before the switchover from RPT to SPT. | The value is an integer that ranges from 15 to 65535, in seconds. |
By default, the interval for checking whether the rate for transmitting multicast data exceeds the threshold before the switchover from the RPT to the SPT is 15 seconds.
The command is applicable to PIM-SM networks.
Before using the command, you must use the spt-switch-threshold command to configure the threshold of the switchover rate. Otherwise, checking the interval is pointless.
